Shares of Diageo plunged 7.0% to $80.81 on September 25 after the London-listed spirits giant announced that Joanne Wilson, currently CFO of advertising firm WPP, will replace Nik Jhangiani as finance chief in 2027. The market's swift verdict: swapping a turnaround architect mid-execution is a risk investors aren't willing to absorb at full price. Diageo Drops 7% After Replacing Its Turnaround CFO — Is a $1.2 Billion Restructuring Now Flying Without a Pilot?
Shares of Diageo sank 7.0% to $80.81 after the world's largest spirits maker announced it is replacing CFO Nik Jhangiani — the executive who built its financial turnaround plan — with WPP finance chief Joanne Wilson, who won't arrive until sometime in 2027. The timing raised eyebrows: Jhangiani stood beside CEO Dave Lewis at a capital markets day less than two months ago to lay out plans to revive growth and cut costs. Now investors are asking who will own the financial blueprint during the most critical phase of execution.
The Architect of the Cost Cuts Is Leaving Mid-Build. Jhangiani oversaw the Accelerate turnaround plan, which delivered $540 million in cost savings in fiscal 2026.
Diageo is investing roughly $1.2 billion in a two-year restructuring , and expects the program to generate about $1 billion in annual savings, with 40% landing in fiscal 2027 and the rest in fiscal 2028. Pulling the finance chief who designed that math, before the biggest savings hit, makes it harder for shareholders to trust the numbers will land on target.
The New CFO Comes From Advertising, Not Spirits. Wilson held senior roles at drinks company Britvic, data-science firm Dunnhumby, Tesco, and KPMG.
Her time at Tesco overlapped with CEO Dave Lewis — a connection that looks more like loyalty than an arms-length search. Analysts say "the key question will be whether Wilson can help accelerate delivery against the financial plan once she arrives."
A Turnaround Already Under Stress Just Got Riskier. Diageo's fiscal 2026 revenue fell 2.97% to $19.64 billion, while earnings dropped 26.2%.
North America, the company's biggest market, saw an 8.4% decline.
The company has already cut its workforce by more than 6%, to about 27,938 employees. With organic sales still shrinking and the person charged with tracking every dollar of restructuring savings headed for the exit, the execution risk rises significantly.
Wall Street Was Already Cautious. In September 2026, no analyst held a "Strong Buy" rating, while 37.5% rated the stock Hold and 12.5% rated it Sell. At $80.81, Diageo now trades roughly 19% below analysts' average 12-month target of about $99. That gap may reflect opportunity — but only if the new CFO can prove she can run a playbook she didn't write.
